Claims. (Cl. 139-154) This invention relates to supports for holding lug straps of looms to picker sticks, and in particular, an improved strap support wherein the parts are adapted to be stamped from sheet metal and wherein the support is frictionally secured in position on a picker stick with an elongated leather strap and a U-bolt and the lug strap I; frictionally secured to the support with another leather positioned against the outer surface of the support. e purpose of this invention is to provide a lug strap support for retaining lug straps on picker sticks of looms in which the parts are adapted to be formed of sheet metal instead of castings whereby breakage and damage to the parts reduced to a minimum.

Conventional lug strap supports, because of the odd design of the parts which normally include an open rect' .tgular shaped frame, are formed by castings or die castings and the extreme shock to which lug strap supports are subjected in use breaks and damages the comparati ely thin brittle castings. With this thought in mind, this invention contemplates an improved method of forming a lug strap support whereby substantially all parts thereof adapted to be stamped from sheet metal and in which he elements are adapted to be readily assembled to form s sport.

is for forming a lug strap support in which a lug s is adapted to be extended around a picker stick positioned between arcuate flanges of sheet metal elements so that the lug straps may be positively secured in position without danger of sharp edges of the sheet metal elements cutting the straps.

Another object of the invention is to provide an improved sheet metal lug strap support that is adapted to be user" in combination with lug straps now in use without changing the lug straps or picker sticks upon which the lug straps are mounted.

Another object of the invention is to provide an improved lug strap support that is adapted to be formed of sheet metal parts in which the parts may readily be assembled by an average mechanic or layman.

A further object of the invention is to provide an improved sheet metal lug strap support which is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies a base having an elongated bar adapted to be positioned against the face of a picker stick with arms extended from upper and lower portions and with a flange on the upper end, an anchor plate having an arcuate flange on the lower edge adapted to be secured to the inner surface of the base, a base plate having an arcuate flange on the upper edge adapted to be secured to the arms on the lower end of the base, a strap of leather or the like adapted to be positioned between the base and surface of a picker stick, another strap of leather r the like positioned against the face of the base and secured between the anchor plate and upper arms of the base and a U-bolt having nuts and lock washers on extended ends adapted to be positioned around a picker 2,766,175 Fatented Oct. 16, 1956 ice stick and extended through the upper arms of the base and anchor plate.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a front elevational view illustrating the improved lug strap support.

Figure 2 is a side elevational view of the lug strap support taken on line 2-2 of Figure 1.

Figure 3 is a vertical section through the lug strap support taken on line 33 of Figure 1 showing the device positioned upon a picker stick, the picker stick being shown in elevation.

Figure 4 is a sectional plan through the upper part of the device being taken on line 4-4 of Figure 2.

Figure 5 is an exploded view showing the base with the face plate on the lower end and with the anchor plate spaced from the upper end.

Figure 6 is a view illustrating a modification wherein the base and face plate are formed integral.

Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved lug strap support of this invention includes a base it havin upper arms 11 and 12 and a flange 13 at the upper end and lower arms 14 and 15 extended from the lower end, a base plate 16 having an arcuate flange 17 mounted on the arms 14 and 15 at the lower end and an anchor plate 13 having an arcuate flange 19 on the lower edge adapted to be secured to the upper end.

The anchor plate 13 is secured in position on the upper end of the base with a U-bolt including a U-shaped strap 29 which is provided with threaded studs 21 and 22, the studs extending through openings 23 and 24 in the arms 11 and 12 and also through openings 25 and 26 in the plate 18 and, as shown in Figures 1 and 2, the studs are provided with nuts 27 and lock washers, as indicated by the numeral 28.

The flange 13 at the upper end of the base extends over the upper edge of the anchor plate 18, as shown in Figure 2, and a cushioning pad or strip, which may be formed of leather or other suitable material, as indicated by the numeral 29, is positioned between the base 16 and the face of a picker stick, such as the stick 311. Another cushioning strip which is also formed of leather or other suitable material and which is indicated by the numeral 31 is positioned between the anchor plate 13 and the base 111. T he cushioning strip 31 is positioned to receive a lug strap, as indicated by the numeral 32, and with the lug strap extended around the cushioning material and base severe shocks, strains and stresses to which the lug strap is subjected are taken by the cushioning elements.

The base 10 is also provided with openings 33 and 34, the sharp edges of which bite into the material of the picker stick or cushioning material against which the base may be positioned providing means for retaining the base in position upon the picker stick.

The anchor plate 18 is provided with openings 45 and 46 which are in registering relation with the openings 33 and 34 of the base it), and rivets or other fasteners may be inserted through the openings 45 and 16, and 33 and 34 to secure the anchor plate 13 in position on the base.

In the design illustrated in Figure 6, the base is formed with an intermediate bar 35, similar to the part 11), with upper arms 3t: and 37 and a base 38 having arcuate flanges 39 and 40 extended from upper edges thereof. The ends of the arms 36 and 37 are provided with slots 41 and 42 that are positioned to receive the threaded studs of a U-bolt with the bar 3% positioned against a cushioning element such as the strap 29 and with a lug strap extended around a cushioning element, such as the element 31 with the device positioned upon the edge of a picker 3 stick. The upper part of the bar 35 may be provided with openings 43 and 44, the sharp edges of which are adapted to bite into the cushioning pad or strip, such as the strip 29 or into the face of a picker stick with the cushioning pad removed.

With the parts designed and assembled in this manner, a base portion, such as the part 10 shown in Figure 5 or the part 35 shown in Figure 6, may be positioned against a cushioning pad on the edge of a picker stick with the upper anchor plate 18 positioned over studs extended from a U-shaped strap, such as the strap 20 and with an additional cushioning pad or leather strip, such as the strip 31, positioned against the opposite face of the base and adapted to extend downwardly, as shown in Figure 2. By this means a lug strap is supported on a picker stick and the lug strap will be retained in position without danger of being damaged by sharp edges of metal parts and the like.

The sheet material, being rolled, is adapted to stand severe shocks, strains and stresses and with the lug strap protected from sharp edges by the cushioning elements the life of the lug strap support of this invention is indefinite.

It will be understood that other modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
